DC DC Switching Controllers datasheet and documents for LTC3875IUH

LTC3875IUH

DC DC Switching Controllers Overview

The LTC3875IUH is a dual-phase synchronous buck controller designed for high-efficiency power conversion. It operates with an input voltage range of 4.5V to 14V and supports output currents up to 120A when paired with appropriate external components. The device features a fixed switching frequency of 400kHz and provides a single non-isolated output, typically configured at 1V. It utilizes DCR current sensing technology to eliminate sense resistors, thereby improving efficiency. The component is housed in a 28-lead QFN package.
